Type: Sportbike

The CBR250 may not be much to look at, but its tiny inline-four can rev to 20,000—Formula 1 territory. That puts it right up there with the spinniest road-legal motors ever. In contrast, Honda’s 2011 CBR250 is made in Thailand and has a single that can spin to maybe 11k—that would have been an entry-level bike than, rather than this half-pint-sized screamer.
